SPECIFICATION formingpart of Letters Patent N 0. 706,136, dated August 5, 1902. Application filed May 31,1902. Serial No. 109,258. (No model.)

To (tZZ whom it may concern:

Be it known that I, MAX \V. \VEIR, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My presentinvention relates to type-writin g machines, and more particularly tomeans for automatically notifying the operator when the bottom of the page is being approached and for automatically locking portions of the machine out of operation when the bottom of the page has reached a predetermined point with relation to the printing-center,thereby avoiding writing too far down on the page or printing upon the platen after the bottom edge of the paper has been fed past the printing-point and conduoing to greater uniformity in ending the pages and avoiding injury to the platen.

A further object of my invention is to provide simple and efficient mechanism of. the character described, which may be regarded in the nature of an attachment, that can be applied to existing forms of type-writing machines and wherein little or no structural change in the machine itself is necessary in order to apply the attachment.

In the drawings, wherein suflicient number of parts of one form of type-writing machine are shown to illustrate my invention in its application thereto and wherein like reference characters indicate corresponding parts in the various views, Figure 1 is avertical front to rear sectional view of a type-writing machine embodying my invention, the section being taken on the line 1 y of Fig. 2 and looking in the direction of the arrow'at said line. Fig. 2 is a plan view of the machine with the keyboard and type-bars omitted and parts broken away. Fig. 3 is a diagrammatic transverse sectional view of the platen and certain of the cooperating parts,the parts being shown in their normal positions with the paper in place on the platen. Fig. 4: is a diagrammatic end View of the platen and certain of the cooperating parts, the parts being shown in their normal positions and corresponding to the positions of the parts in Fig. Fig.

' key 5 and a restoring-spring 6.

Fig. 6 is a diagrammatic end View of the parts illustrated in Fig. 4 and shown in the positions which correspond to the disposition of the parts in Fig. 5. Fig. 7 is a View similar to Fig. 6, except that the parts are shown in the locking position. Fig. 8 isa fragmentary longitudinal sectional view of the left-hand portion of the platen. Fig. 9 is a detail perspective view of the guiding or restraining block. Fig. 10 is a detail perspective view of the shield, to be hereinafter described. Fig. 11 is an enlarged detail fragmentary sectional view of one of the supporting-brackets and certain of the cooperating parts, the section being taken on the line 2 a of Fig. 2 and looking in the direction of the arrow at said line.

Fig. 12 is an enlarged detail perspective view of the actuating-slide.

I have shown my invention applied to a No. 6 Remington machine, though obviously the invention may be applied to other characters of type-writing machine and various changes in the construction may be made to facilitate such application. I i

The frame 1 is surmounted by a top plate 2, and key-levers 3 are fulcrumed at tin the frame and are each provided with a finger- The key-levers are each connected at 7 to a two-part link 8, which is pivotally connected at its upper end to an arm 10, that extends from a type-bar 11, pivoted at 12 to a hanger 13, that is secured by a screw 14 to the top plate. EX- tending beneath the key-levers 3 and the levers 15 of the space-bar 16 is a universal bar 17, that is connected to upright links 18, hung at their upper ends 19 on the transverse bar 20 of the dog-rocker 21, which carries feeddogs 22, that cooperate with an escapementwheel 23, operatively connected to a feed-pinion 24, that meshes with a feed-rack 25, pivoted to the paper carriage or truck 26, that carries traverse-rollers 27, which bear upon the traverse-rod 28 and is guided by a traverse-rod 29, both of said rods being supported upon the top plate of the machine. Connected to the truck by links 30 is a platen frame or carriage 31, which carries a grooved traverse roller 32, that cooperates with a shift-rod 33 and by means of which the platenframe may be shifted transversely for upper and lower case writing. The carriage is connected to one end 34 of a band 35, that has its opposite end connected to a spring-drum 36. The platen-frame 31 carries a platen 37, a line-spacing ratchet-wheel 38 being secured to the right-hand end thereof, and a linespacing pawl 39, controlled by a hand-lever 40, cooperates with the ratchet-wheel to effect a rotation or line-spacing movement of the platen.

Thepaper-feed rollers 41 are mounted upon a shaft, which is supported upon arms 42, that are pivoted to ears 43 on a fixed crossbar 44 of the platen-frame and are released in the usual manner by an arm 45, that is se cured to'the rock-shaft 46. The parts thus far described constitute portions of the wellknown No. 6 Remington machine, and a more detailed description thereof is unnecessary.

The T-shaped end bars 31 of the platenframe 31 have brackets 47 and 47 removably secured thereto. Each of these brackets consists of an engaging finger 48, which is adapted to engage under the top and on the inner side of its end bar, as shown in Fig. 11, and a downwardly-extending lug 49, that projects down on the outside of the bar. This lug 49 is tapped to receive a screw 50, the stem of which passes through the tapped opening in the lug and bears at its inner end against the flange of the end bar, so as to securely connect the bracket to the platen-frame. Each bracket is provided with an upwardly-extending arm 51, that on the left-hand bracket being tapped to receive the stem of a screw 52, that has a coned end which constitutes abearing for one end of a rock-shaft 53, which extends throughout the length of the platen adjacent to the point of introduction of the paper. The bracket 47 is apertured to receive and constitute a bearing for the opposite end of the shaft. One end 54 of a coiled spring 55 is secured to the platen-frame near the left-hand bracket, whereas the opposite end 56 of the spring is connected toa crankarm 57, that is secured to the rock-shaft 53, as show in Fig. 2, so that the tension of the spring is exerted to turn the rock-shaft in the direction of the arrow in Fig. 1. Secured near the center of the rock-shaft 53'is adownwardly-extending finger58, formed integral with a sleeve 59, which surrounds the shaft and carries a set-screw 60, that passes through a threaded opening in the collar and bears at its inner end against the rock-shaft, thus securing the finger and rock-shaft together. The tension of the spring 55 tends to turn the rock-shaft so that the finger will be projected across the path of the paper 61 as it is introduced into the machine, as will be apparent from an inspection of Fig. 5. The finger projects through a slot 62, Fig. 10, in a papershield 63, which is bent at 64 to surround the shaft 46 and be supported thereby, and the lower end of the shield or guide is bent at 65,

where it is adapted to rest upon the usual paper-apron, (not shown,) and thus constitutes a guide for directing the paper to the bight between the feedrollers 41 and the platen 37, asindicated in Fig. 3, and the paper as it is introduced will tend to deflect the finger from the position shown in Fig. 5 to that indicated in Fig. 3, thus turning the rock-shaft 53 against the tension of its spring, or the screw may be employed as a fingerpiece to turn the shaft, and thus move the finger 58 out of the path of the paper and permit it to be freely introduced to the bight between the feed-rollers and platen. After the paper has been so introduced the finger-piece or screw 60 may be released, thus permitting the finger 58 to bear under the tension of the rock-shaft spring upon the upper face of the paper, while the lower face is supported beneath the finger by the shield 63, as shown in Fig. 3.

The left-hand end of the platen has a socalled locking-wheel 66 secured thereto between the usual platen-head 67 and the body of the platen, the usual platen-head screws 68, Fig. 8, passing through holes in the platenhead and through corresponding holes in the body of the locking-wheel. One face of the locking-wheel is recessed to receive the platen-head, so as to reduce the thickness of the wheel and not add materially to the len gth of the platen. This locking-wheel has peripheral depressions 69 therein, which form teeth, and these depressions are adapted to receive a pin 70, that projects inwardly from a platen-locking device 71, which is pivoted.

at 72 to the crank-arm 57, hereinbefore referred to. The lockin g device carries an out.- wardly-projecting pin 73, that is adapted to abut against the arm 57 and limit the movement of the device in one direction relatively to the arm. A coiled contractile spring 74 is secured at one end to a pin 75 which projects from the locking device, and at its opposite end to a pin 76, which projects from the crank-arm 57, thus tending when the parts are in the positions shown in Fig. 4 to maintain the locking-pin out of engagement with'the locking-wheel.-

The locking device has a rearwardly-extending abutment trip or stop 77 formed thereon, and this stop is seated in the groove 78 of a guiding or restraining block 79. (Shown in detail in Fig. 9.) The block is provided with apertured ears 80, which form a bifurcation 81 between them. The shaft 46 extends through these ears, Fig. 2, and the boss 45 of the arm 45 (for actuating the shaft 46) is seated on the shaft in the bifurcation of the block, and the boss and arm being secured to the rock-shaft by a set-screw 82 prevents the block from moving along the shaft. The purpose of the block is to afford a supporting means for the abutment 7 7 to prevent a lateral deflection thereof when it contacts with a cooperating abutment on the frame of the machine, as will hereinafter more clearly appear.

Supported upon the top plate of the machine is a slide 83, which is shown in detail in Fig. 12. Thisslide has a slot 84, and the stems of headed screws pass therethrough and into threaded openings in the top plate to guide the slide andlimit the movement thereof transversely of the machine or in the direction of the travel of the carriage. The slide is in the nature of an angle-iron, which has a base portion through which the slot 84: is formed, an inclined bracket-like portion 84 and a supporting part that extends to the right of the part 84 Fig. 2, and from which stop-pins or abutments 86 project upwardly and extend in a series in the direction of the travel of the carriage. The slide is also apertured at 87 for the reception of a bent end of a stiff spring 88, whichisloosely coiled around a screw 89, projecting upwardly from the top plate and extending rearwardly where the end 90 extends to the right of a depending arm 91 of a longitudinally-movable rod or bar 92 of the line-lock mechanism, which mechanism is illustrated in the present instance as the same as that employed on the No. 6 Remington machine and for which a patent was issued to George B. Webb February 22, 1898, No. 599,4:28, though it should be understood that any suitable line-lock mechanism may be employed. The line-lock mechanism comprises the longitudinallymovable rod or bar 92, which is movable on pivot-pins 93 and is normally maintained toward the right by a spring 94:, as will hereinafter more clearly appear. This bar 92' has a downwardly-projecting pin 95 extending from the lower side thereof, Fig. 2, and which v is to the right of arearwardly-extending pin 96 on a line-locking device 97, that is pivoted at 98 to a bracket 99, secured to the top plate. The device 97 has an arm 100, that projects in the direction of the travel of the carriage and is adapted to be moved down in front of a locking-finger 101 on the dog-rocker and prevent a forward movement thereof, and thus prevent adepression of the universal bar and finger-keys.

The spring 94, hereinbefore referred to, normally maintains the free end of the locking-arm 100 out of the path of the finger 101 on the dog-rocker and at the same time causes the pin 96 to bear on the pin 95 to maintain the bar 92 toward the right.

The stilf spring 88 is loosely seated on the screw 89 and normally affords no tension upon the parts, the screw merely acting as a pivot upon which the spring turns, and while the action of the spring is in the nature of a lever it also has a resilient function, as will hereinafter appear.

In the operation of the device the paper is inserted in the machine in the usual manner after turning the spring-pressed finger 58 out of the path thereof, as indicated in Fig. 3. This results in turning the rockshaft 53 against the tension of the spring 55. The finger 58 will at this time bear upon the upper side of the paper,and the pin 7 O and abutment or trip 77 will be maintained out of the engaging or operative position, as illustrated in Fig. 4. The operator may continue to write until the edge 61 passes beyond the finger 58, as illustrated in Fig. 5, when the paper no longer constitutes a support for the finger, and the spring 55 turns the rockshaft and forces the finger into the aperture 62 in the shield 63. This results in moving the locking device from the position shown in Fig. 4: to that illustrated in Fig. 6, thereby bringing the locking-pin 70 into a depression 69 in the locking-wheel. A rotation of the platen in the direction of the arrow in Fig. 6

for one, two, or three line-space distances,

accordingly as the line-spacing is set for half, full, or double space distances, will result in moving the locking device 71 from the position shown in Fig. 6 to that illustrated in Fig. 7, when further movement thereof will i be arrested and the locking-wheel and platen will be prevented from further rotation. The movement of the locking-piece 71, just described, carries the abutment or trip 77 into the path of the pins 86 on the slide 83. Should the carriage be at the left-hand side of the machine and the operator attempt to return the carriage to the right to begin a new line of writing, the trip 77 willbe brought into contact with the pins 86 and the slide 83 will be moved for the limited distance with the carriage toward the right.

pivot 89, at the same time placing the spring under tension,and effect a longitudinal movement of the bar 92 toward the left, which movement of the bar results in a depression of the locking-arm 100 through the pins 95 and 96. A depression of the locking-arm 100 projects it into the path on the dog-rocker, and the dog-rocker, universal bar, and finger keys will be locked against operation. It will be understood that only a comparatively slight movement of the carriage from the extreme left-hand position toward the right is permitted before the trip 77 is brought into contact with the stop-pins 86, so that the operator is warned when the end of a page has been reached. The locking of the finger-keys against depression and the locking of the platen against line-space movement, howthe pin 70 from the depression 69 in the lock- This move .ment is effective to turn the spring 88 on its ingwheel, and the tension of the spring74 will restore the device 71 to the normal position indicated in Fig. 4, thereby at the same time moving the trip 77 away from the pin.86, with which itis in contact, and the slide 83, spring 88, and line-locking mechanism will be restored to the normal or unlocked positions by springs 88 and-94c and the carriage is free to be moved in either direction and the platen is free to be rotated to effect a linespacing movement. When the end of the page passes the finger 58 and the pin 71 engages the locking-wheel, one or .more linespacing movements of the platen may be effected,or the platen maybe rotated until the locking device 71 has reached the limit of its movement, as indicated in Fig. 7. As before explained, this limit of line-spacing movement of the platen after the pin engages the locking-wheel is dependent on the character of the line-space and the platen will'be arrested from rotation accordingly as a half, full, or double line-spaceis employed; butin any event the platen is always looked against rotation when the edge 61'of the paper reaches a certain distance from the printing-center.

If the locking device 71 is moved to the position shown in Fig. 7 when the carriage is at the extreme right,'a movement of the carriage from right to left will be prevented, and if the carriage has traveled to a position where the trip or abutment 77 is opposite a space between two of the pins 86 and locking device 71 is moved to the position shown in Fig. 7 at this time a movement of the carriage in either directionis prevented or limited.

From the foregoing description it will be understood that means are provided which are controlled by the paper for affording an actuation of the line-locking mechanism for arresting a line-spacing movement of the platen and for preventing a complete travel of the carriage in either direction when the bottom-edge of the paper reaches a predetermined point with relation to the printingcenter and that the operator is not only warned by locking the several parts referred to, but is actually prevented from operating the machine either to move the carriage, to turn the platen, or to depress the finger-keys.

While I have shown one manner of carrying out my invention, it is obvious that various changes may be made without departing from the spirit of my invention and that certain features of the invention may be employed with or without the others.
